Sealed Judgement

Based on the above assumptions, demand for the internal demand component of the rainwater tank
was calculated as:

x   25 L/d (per person) + 21 L/d (per person) x 2 people per dwelling (peak) = 92 L/d; and

x   Daily demand (representing indoor use) = 92 L/d * 16 units = 1,472 L/d = 1.472 kL/d.

For modelling, 5-kL of the overall rainwater tank volume was adopted for each cabin (8 x 5 kL =
40 kL). As noted above, this volume is separate to the detention tank volume adopted with respect
to quantity.
Figure 4-2 shows the pre-development MUSICX setup, while Figure 4-3 shows the post-development
model setup.
